In this chapter, we looked at Linkerd, which provides a very smooth and easy install process. Linkerd is an attractive option in certain environments as a service mesh. Linkerd provides the Linkerd CLI, which runs on either Linux, Windows, or MacBook to offer an easy way for us to install its control plane if we only have kubectl access to the remote Kubernetes cluster. 

Automatic sidecar injection through the admission webhook controller allows us to easily place all the already deployed applications into a service mesh data plane. The web dashboard of Linkerd provides instant insights into the control and data planes. Linkerd relies upon an external Ingress gateway.

In the next chapter, we will explore the traffic management capabilities of Linkerd. In the vocabulary of Linkerd, traffic management is termed reliability.
